如上的一个xml。我想获得每一个Field节点的Name中的值和对应的value值，value分割成数组取第一个的值，最好用org.w3c.dom解析。

Answer 1

import java.io.File;
import java.util.Iterator;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class ParseXml {
public static void main(String[] args) throws DocumentException {
SAXReader reader = new SAXReader();
Document doc = reader.read(new File("d:/test.xml"));
Element root = doc.getRootElement();
Element record = root.element("Record");
Iterator<Element> it = record.elementIterator("Field");
while (it.hasNext()) {
Element element = it.next();
Element name = element.element("Name");
System.out.println(name.getText());
Element value = element.element("Value");
ParseXml.parseValue(value);
}
}

public static void parseValue(Element value) {
Iterator<Element> it = value.elementIterator();
if (it.hasNext()) {
while (it.hasNext()) {
Element element = it.next();
Element innerField = element.element("Field");
Element innerName = innerField.element("Name");
System.out.println(innerName.getText());
Element innerValue = innerField.element("Value");
parseValue(innerValue);
}
} else {
System.out.println(value.getText());
}
}
}
